3.18 Gibb's Free Energy

  • When (delta) G is less than 0, it is spontaneous

  • when (delta) G is less than 0, more products are made.

  • Both are favorable to the forward reaction

  • both are unfavorable to the forward reaction

  • To find the point at which a reaction changes from being thermodynamically favorable to unfavorable, set (delta) G to 0 and solve for T, or:

Free energy of formation
